Situs Inversus » General
Q89.3

Definition:

Transposition from one side to the other around the sagittal plane of all or some major structures within the thorax and abdomen.
The heart, the stomach and spleen are located on the right side, and the liver and gall bladder on the left. The left lung is trilobed and the right lung bilobed, and blood vessels, nerves, lymphatics and the intestines are also transposed.
If the heart is swapped to the right side of the thorax, it is known as situs inversus with dextrocardia or situs inversus totalis. Otherwise is called situs inversus incompletes.
